Filed:

Mar 9, 2012

Appl. No.:

13/416005

Inventors:

Jeff Dewberry - Bremen GA, US
Frank Calhoun - Carrollton GA, US
Robert Creed - Carrollton GA, US

Assignee:

Southwire Company - Carrollton GA

International Classification:

A47F 3/14

US Classification:

211 601, 2111267, 2111811

Abstract:

A stem may comprise a circular base, a plurality of outer ears, and a plurality of outer uprights. The circular base may have a circular outer perimeter centered on a center point of the circular base. The plurality of outer ears may protrude outwardly from the circular outer perimeter. The plurality of outer uprights may be respectively connected to each of the plurality of outer ears at a bottom end of each of the plurality of outer uprights. The plurality of outer uprights may be substantially parallel with each other and may be substantially perpendicular to the circular base. The stem may be configured to allow an additional stem to mateable stack inside the stem. The additional stem may be rotated (with respect to the stem) an incremental amount such that sides of outer ears of the additional stem may respectively contact sides of the outer uprights of the stem.

International Classification:

B23P 11/00
B23P 19/04

US Classification:

29428, 292811

Abstract:

A workstation and method for the installation of a pulling head assembly onto one or more conductors of a cabling system are provided. The workstation incorporates one or more of: a conductor clamp that holds the conductors of the cabling system in place during the installation of the pulling head assembly; a cutting guide having indicia marks that indicate the lengths to which to cut the conductors in order to achieve a staggered pattern of pulling eyes attached to the conductors in the pulling head assembly; a stripping tool that is used to remove a portion of the insulation from the terminal end of each conductor so that the end of the conductor may be inserted into the pulling eye; and a crimping tool that is used to crimp the pulling eyes onto the terminal ends of each of the conductors.

International Classification:

B65H 49/26

US Classification:

2425985

Abstract:

An improved pay-off assembly allowing cable loaded on a cable reel to be transported to an installation site and/or paid-off during a cable pull is described. The pay-off assembly may include one or more of lateral support braces that provide stability and strength to an A-frame structure supporting the cable reel; a reel lock assembly for securely holding the cable reel in place during transport and/or pay-off of the cable; an end cap assembly that prevents detachment from an arbor as the arbor and cable reel rotate during pay-off; a dog hole stop assembly that engages a “dog hole” in the cable reel to prevent the cable reel from rotating during transport; a braking system for controlling the rotational speed of the cable reel during pay-off; and a ground attachment assembly that allows an additional cable reel to be loaded for transport and/or pay-off of the cable.
